PENCIL ATTACHMENT FOR. FOUNTAIN-FEMS.

application filed September 4, 1917. Serial No. 189,514.

To all whom it may concern:

Be it known that T, Annonn L. Green- HEIM, a citizen of the United States of America, residing in the State of New York, city and county of New York, have invented certain new and useful Improvements in Pencil Attachmentsdor Fountain- Pens, of which the following is a full, clear, and exact description.

This invention relates to a pencil attachment for fountain pens, being particularly adapted for fountain pens of the compressible sack self filling variety for the reason that leakage of ink through the pencil section is less liable to take place. Aside from the novel combination referred to, certain mechanical features adapting the combination' for assemblage are resorted to.

' I will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claim, reference being had to the accompanying drawing forming art hereof, wherein,

igure 1 1 lustrates my improved combination in elevation;

Fig 2 is-an enlarged fragmentary longi tudinal sectional view;

Fig. 3 is an enlarged deta'l View of the pencil holding mechanism;

Figs. 4 and 5 are cross sectional views on 7 lines 33 and 4- 1 respectively in Fig. 2;

" a. rotatable tube 18 is located having a lon-' and Fig. 6 is a fragmentary longitudinal sectional view of a modification of my invention.

As herein illustrated, my improvement consists of a barrel 6 in two sections 7' and 8, the section 8 having a pen section 9 at one end thereof and also containing a compressible sack 10 to retain ink. To compress the sack in order to fill same, a lever 11 pivotedat 12 to the section 8, and bearing upon a shoe 13, is utilized. The construction for a self filling fountain pen is well known and needs no further description; As can be seen, the section? is reduced at 14:, said reduced portion being provided with threads to engage the threads in the'open end of the section-8.

Within the section 7 I place a pencil holding device 15, consisti of a fixed tube it having a spiral slot 17. Within the tubelt gitudinal slot 19. Within the l tted tube 18 a pencil point retaining tube 20 is located havlng a pin 21 extending through the slot 19 into the spiral slot 17 in the fixed tube 16, the tube or pencil holder is longitudinally movable. To hold the tube 16 stationary I provide a locking device 22 consisting of a corrugated cylindrical block which is secured to a casing 23 which surrounds the tube 16 and which is fastened to same or driven in. To secure the rotatable slotted tube 18 to the rotatable head 28 of the pencil section, I provide same with acorrugated cylindrical block 25 to engage the rotatable head. The head 24 is further provided witha central bore 26 to receive the pencil point retaining tube 20.

The rotatable head 24 and tube 20 are held together by the corrugated block 25 which is secured to said tube and forced into the rotatable head. After the head 24 and pencil device 15 are assembled in the manner described, the projecting part of the pencil device will'be inserted into the bore 7 of the section 7 and driven in to cause the block 22 to grip the said section 7. The corrugations of the blocks 22 and 25 will be forced into the wall of their respective barrel members and be firmly embedded therein, as shown in Figs. 4: and 5. When the head 24 is rotated, the pencil will be moved to extend from the end of said head for use or contraction into the head. The blocks 22 and 25 are eflective means for connecting the pencil holding device and the barrel sections without resorting to rivets or the like. For an ordinary pen, that is a fountain pen that is not a selffiller, plug up one end of the section 7 as shown at 26 Fig. 6, hence there can be no leaking from the ink reservoir through the pencil'section. In the form of pen illustrated in Fig. 1, there can be no leakage as the sack contains the ink.

What ll claim is:

In combination, a pair of tubular sections 'of uniform diameter, a head fitting frictionally in one of said tubular sections flush with one edge thereof, a tube having one d fitted 'frictionally within said head and its main body disposed concentrically within said last-named tubular section, a tube longer than the other tube projecting into saidother tube and having a flange adapted tei age the er edge merecf so to belted in movement in one direction at cordingly, a head frictionally attached upon the projecting end of the longer tube, and engaging the adjacent edge of the first head so as to confine the longer tube against 10ngitudinal displacement, the other tubular section being attached over, so as to rotate together with said longer tube, and means for advancing a pencil point out of the lastnamed tubular section when said last-named head and tl'lbe are rotated.

Signed at New York city, N. Y., this 30 day of August, 1917.
